ILLINOIS- y ofthe UnitedStates, residing at Chicago, in the countyofCook andl State of Illinois, have invented certain new and useful Imfproif'ements in Carbureters, of which the l ments. in carbureters forexplosion or hydro carbon' enginesof various types for' variouspurposes,fbut more particularly for gasolene Venginesrfor operating'automobiles and inoitorfboats; and it consists incertain peculiaritiesof the construction, novel` arrangement andoperationof the various partsthereof, as 'will be hereinafter more fully set forth andspecificallyclaimed.v i

The principal` objects of the invention are to `simplify theconstruction of such car-` bureters; to improve their generalefficiency; andto provide earbureters which .shall be compact in forni,simple,V and of such construction as to provide means to adjust andmaintain during its operation the proper proportions ofairandhydrocarbon admitted thereto, also to introduce the air to the,"carbureter so as to produce more thorough and complete mixture than Aisordinarily donezfl to provide automatic means for the admission of lairto the carbureter in propel' proportions coiistantly1-` and under"different suctionsof the engine.l Various other o bjects and advantagesof the invention will.

lie-disclosed inthe subjoined description and explanation. Y I, l.

A f' Likenumerals of reference refertoieorresponding `parts throughout `the.different views of the drawings.

`T he casing ofthe carb-ureter is pre-ferably.`

formed of upper and lower parts ltlfa'nd `1l, respectiyely, which` arehollow and have meeting flanges 1Q, and 13, on theii; lower and upperportions respectively, which:

flanges may be secured together by bolts 15,

extended through suitable openings therein.` The upper portion 10. ofthe casing, is provided with an extension or conduit 16for the outlet ofthe mixture ofair and hydrocarbon, which etension or conduit hascoininunicationwwith the engine (not shown),- and `may be connectedthereto in any fsuitable manner.' Located within the part 10, :butspacedtherefrom,,is a receptacle 17, forthe retention and circulation ofhot water, whiohf may be supplied.v thereto througha conduit 1Q, in thelower portions of1 the parts 10and 1T, and Vmay be discharged through aconduit 19, in said parts. preferably at a pointabove the `inletconduit. In `the present instance, the part-10, of the casing. and'thereceptacle 1T, therein, as well asihe conduits 18,7and

19. are shown as being lformed integrally with one another, but .itobvious that they nia'y be separate parts but located with` re` i i'PateiitedMai'r-, 1912. Application filed October24 1910. Serial No.588,834. i i .l

`for the upward 'passage ofihyd'rocarbon and gscrew-threaded andhasadjustably mounted eid in place on the stem 23, by means of a nut2 6,on the lower portion of said stem.

The-fcollar 25 is provided with a recess 27, vwhich may' extend aroundsaid collar and is for the part 1,1, of the casing, may rest.

air regulating band is provided with 'an ex-l the reception of thennerend of an adjusting screw 28, which is horizontally located in asuitable opening formed in the lower portions of the-casing 10, andreceptacle 17, as -is clearly shown in Figs. 1, and 2, of the drawings.Surrounding the valve stem 23, and resting at one of its ends againstthe upper portion of the collar 25, and at its other end against'thepartition 22, is a spring 29, which actuates the needle valve in onedirection. Mounted on the upper-.end of the valve stem 23, is a head 30,which has at its upper end a laterally disposed. projection 31, betweenwhich and the lower portion of said he'ad, is formed a transverse recess32, Vfor an eccentric 33, which is fixed on a shaft 34,

which shaft is horizontally and transversely' journaled in the upperportion of the part 10, o'f the casing. v The lower part 11 of thecasing, is provided at its lower end with a'series of openings 35, forthe admission of air, and is` preferably provided on its inner surfacewith an inwardlyv extending annular-flange 36, located just above saidopenings, against the lower surface of which flange, a band 37, having aseries of openings 38, which may be brought to register with theopenings S''hin 1s tension 39, which projects through a suitable openingor slot inthe wall of the part 1 0, by

means of which projection the said band or regulator may be turned so asto cause the openings 38, therein to register with the vopenings 35, inthe casing, or when desired,

to throw the samevout of register. Secured on the lower end of the part11, is a plate 40, on which the lower surface ofthe regulator 37, willrest. The `upper portion of the part 11, is provided on its innersurface with a valve seat 41 for the valve 42, for the from the wall ofthe part'11, and then upi carbureting chamher. Extended inwardly wardlyand centrally therein, is an extension 43, the upper portion of which isprovidedwith a socket 44, in which is fitted a plug 45, having a channelor port 46, therethrough, and provided at lts upper end with a taperedvalve seat 47, ,for the tapered end of the needle valve 24, whichco-acts with said seat to regulate the flow of hydrocarbon through theopening in' said plug. The ex? -tension 43, is rovidedwith ar channel48, which communicates at oneof its ends. with the channel 46, inthesaid plug and at its other endwith thechannel 49,0f a .pipe 50,

which may be suitably secured in an opening fumano 51, formed in thepart 11, ai the casing.

T hebuter p ortion of the pipe of connection 50, is provided with anupward extension 52, .which has a' valve chamber 53, for a floatoperated v alve 54, which is seated in the ,upperI portionof said.chamber. The.

llower part ofthe chamber 53, is provided with a drain-cock 55, and theupper part of the extension 52, has mounted thereon a're.

ceptacle 56, which has communication withl the channel 49, and valvechamber 53, as

shown in Fig. 1, and Said vessel or receptacle has mounted on its upperend'a cover 57, which is provided with a vent opening` 58, and a centralopening 59, through which the upper portion of the valve stem 60, is

extended. This stem has mounted thereon withln the vessel 56, a float'61, to lactuate the valve 54, on the lower end of said stem.

The pipe' or connection 50, has communication at its outer end witha'supply of hydrocarbon, not shown.

Mounted on the upper end of the extension 43, is an air dlstributer 62,which `is provided with a series yof upwardly tapered openings 63, whichcommunicate at their 'upper .ends with the carbureting chamberl aroundthe plug-45, so that thev air passing through said openi-ngs willcomminglewith the hydrocarbon asit is discharged through.

the discharge portA or channel 46, in said plug. The valve 42 for thecarbureting chamber is provided with a peripheral flange 64, which is.upwardly and outwardly inclined, to correspondv lwith the inclination'of the seat 41, for said valve, and -is provided wit-h a series ofopenings 65, which are inwardly directed as 1s clearly' shown in Figs.1, and 4, ofthe drawings. At its cen. tral portion, the valve 42, isprovided withV a hollow'depending extension 66, in the uper poiftion ofwhich the airl distributor 6,2,

1s located. The lower part of the extension 66, is providedl withopenings 67, for lthe passage' of 'air from ,t 1e air chamber 68, whichis formed by the lower part 11, of the casing." Gommumcating-4 at one ofits ends with theair chamber 68,.is an air inlet pipe 69, which'has itsouter portion downturnd and lcrew-threaded to, engage a cap 70, whichisprovided Awith a series of openings 71, 72, and 73, preferably ofdifferent sizes. These openings are governed by ball valves 74, 75, and7 6, respectively, which balls ai'e referably of diiferent sizes andareguarded hy means of arches 77, located directly over said valvesandmounted on a foraminous member'v or .plate 78, in screw-engagement withthe inneru per surfacefof the cap 70.
